degrees. and 93 in manassas. typically, this would be a hot day. look at the heat index right now. and this is the way it feels on the exposed skin. 112 in fredericksburg, 109 in la plata, 103 in leesburg, and frederick, maryland coming in at 106 degrees. this is an extensive heatwave across the country. >> anywhere you see that lighter shade of red, that includes chicago, st. louis, kansas city, cincinnati, detroit, washington, new york, philadelphia, all under excessive heat warnings now. it's no longer a watch, it is now a warning, because this is definitely going to happen across our area tomorrow. expect the heat index between 105 and 110 degrees. and i think it's going to get even warmer during the day on friday. friday is really the day to watch out for that heat index. it could approach 115 degrees, and in some areas could even approach 120. that is hot weather, and once again, we do not see that very often. i'll be back in just a little while to let you know just how long this is going to last. >> whew. >> all right, thanks, doug.
